Qatar's central bank said it sold 1 billion Qatari riyals ($274.7 million) worth of treasury bills in a monthly auction on Wednesday, with yields higher than in its previous offer.

The bank sold 650 million riyals of three-month notes with a yield of 2.25 percent, higher than the 2.14 percent yield at which the bank sold 750 million riyals one month ago in a sign that sanctions against Qatar continue to exert pressure on liquidity in the Qatari money market. It sold 350 million riyals treasury bills with a six-month maturity and a yield of 2.49 percent, it said on its website.
